Should I take collagen before or after workout?

Why whey goes after, and why collagen's one workout timing runs the other way

Should I take collagen before or after a workout is a question lifters answer by analogy with whey, and the honest page's point is that the analogy runs backwards, because the one reason collagen has a workout timing puts it on the other side of the session. Why whey goes after: a resistance session is the stimulus, and the leucine dose in twenty to forty grams of a complete protein is the trigger that switches muscle protein synthesis on once the stimulus has been provided, the synthesis literature's sequence, so whey goes after the session, or at the next meal, with the window generous enough that a meal within a few hours does the job, and a lifter who has spent years taking a shake after training has the order right for whey. Why collagen's one workout timing runs the other way: the tendon pre-loading protocol, the only collagen research with a clock attached, gave around 15g of gelatin or hydrolysed collagen with roughly 50mg of vitamin C about an hour before a loading session, the gelatin and vitamin C literature's design, and the reason is kinetic, collagen peptides and amino acids appearing in the blood within about half an hour and peaking around the hour, the amino acid kinetics literature's curve, so a dose an hour before puts the substrate and the cofactor in the blood at the moment the exercise raises collagen synthesis in the loaded tendon, whereas a dose after the session arrives once the stimulus has passed, the reverse of whey's logic because a tendon's builders want their material during the load and a muscle's want theirs after it. So a reader on the tendon protocol takes collagen an hour before the session and whey after it, two supplements on opposite sides of the same workout for two different tissues.

The reader with no workout timing, what the forums are arguing about, the practical order for each reader, and the timing filed

The reader with no workout timing is most readers. A lifter taking collagen for skin, for a general reason or for the joint trials' dose is taking it on a clock of weeks, the skin trials specifying no time of day and measuring at eight to twelve weeks, the joint trials at months, the skin turning over in around four weeks in its outer layer and far more slowly beneath, so the workout is irrelevant to that reader's collagen and the dose goes whenever the habit holds, with breakfast, in an evening drink or in the post-session shake with the whey for convenience, the habit literature's finding that an anchored dose survives where a floating one lapses, and the only rule being consistency across the weeks. What the forums are arguing about, when before against after fills a thread, is two reasons talking past each other: the before camp is quoting the tendon protocol, correctly, for a reason most of the thread does not have, and the after camp is applying whey's logic to a protein that does not carry whey's leucine and has no post-session job, so both are right about their reason and wrong to generalise it, and a reader who names their reason has the answer without the thread. The practical order for each reader: on the tendon protocol, collagen and vitamin C in water about an hour before the loading session, whey and creatine after; for skin or a general reason, collagen whenever, whey after, creatine any time; and never collagen instead of whey after the session, since collagen carries almost no leucine and the post-session shake is whey's, the counting pages' two columns. The register's lines are unchanged by any timing: no claim for collagen, vitamin C's collagen formation sentence beside it, and protein's muscle sentences for the whey. The timing filed: whey after for the leucine trigger, collagen an hour before for the tendon protocol only, no workout timing for skin or a general reason, the forum argument as two reasons talking past each other, and the practical order for each reader, with the worked example being two capsules whenever the habit holds, £16.99 for 120 at 28p a day.

The verdict, before for the tendon protocol, after for the whey, and whenever for everyone else

Should I take collagen before or after a workout: backwards from whey, whey going after the session or at the next meal because its leucine dose switches muscle protein synthesis on once the stimulus has been provided, and collagen going about an hour before for the one reason with a workout timing, the tendon pre-loading protocol, which put around 15g of gelatin or collagen with vitamin C in the blood, peaking around the hour, ahead of the loading stimulus that raises collagen synthesis in the tendon, so that a reader on the protocol takes collagen before and whey after, a reader taking collagen for skin or a general reason has no workout timing and takes it whenever the habit holds, and the forum argument is two reasons talking past each other. Two capsules whenever the habit holds: Futuro Labs Marine Collagen, 1200mg type 1 with 12mg vitamin C, 120 for £16.99 at 28p a day.

Questions people also ask

Is it better to take collagen before or after a workout?

Before, about an hour before, if the reason is the tendon pre-loading protocol, which put around 15g of gelatin or collagen with vitamin C in the blood ahead of the loading stimulus, and neither if the reason is skin, joints or general, since those trials specified no time and run on a clock of weeks, with whey after the session for the leucine trigger either way.

Why do people say to take collagen before a workout?

Because the tendon pre-loading research did: collagen peptides peak in the blood around an hour after a dose, and the protocol timed around 15g with vitamin C an hour before a loading session so the substrate and the cofactor were present when exercise raised collagen synthesis in the loaded tissue, a research adjunct for a physiotherapist's programme rather than a rule for everyone.

Can I take collagen and whey together after a workout?

Yes, for convenience, if the collagen is for skin or a general reason: the two do not interact and the post-session shake is a reliable anchor, with the whey doing the muscle work and the collagen counted on the label rather than toward the muscle target, and never the collagen instead of the whey, since it carries almost no leucine.

Does collagen help muscle recovery after a workout?

No: collagen carries almost no leucine and no tryptophan and produced the smaller anabolic response in the direct comparison trials with whey, so it has no post-session job, and the one workout timing collagen has is before a loading session for a tendon, not after one for a muscle.

What does reddit say about collagen before or after a workout?

The threads split into a before camp quoting the tendon protocol and an after camp applying whey's logic, and both are right about their own reason and wrong to generalise it, so a reader who names why they take collagen, a tendon programme, skin or general, has the answer without the argument: before for the protocol, whenever for the rest.
